Senior React Native Engineer

Senior React Native Engineer

About the Role

VALA is building the financial layer for culture — a social video platform where every interaction moves real value on-chain.

We’re looking for a Senior React Native Engineer who understands how to make mobile experiences feel effortless. You know how to keep the UI thread free, how to avoid jank, and how to make navigation feel native and fluid.

You’ll take ownership of our live mobile app and push it toward production-level precision. This role is for someone who obsesses over responsiveness, gestures, transitions, and every frame that defines how users feel the product.

What You’ll Do

• Optimize the UI thread and prevent blocking operations.
  

• Profile and tune JS-to-native performance for consistent 60fps.
  

• Deliver native-quality navigation and transitions that feel instant.
  

• Implement optimistic UI updates and prefetching for snappy feedback.
  

• Refine video playback, caching, and lifecycle behavior for seamless scrolling.
  

• Apply React Native best practices around concurrency, memory management, and state control.
  

• Collaborate closely with design to bring interaction and motion to life.

You Bring

• Proven experience with video-heavy or animation-rich apps
  

• Experience with React Navigation, gesture handling, and concurrent rendering
  

• Ability to use optimistic updates, prefetching, and caching for great perceived performance
  

• Comfortable debugging across iOS and Android
  

• Bonus: experience with Web3, wallets, or blockchain integrations
  

Why VALA

VALA connects social media and real value in real time. Every like, tip, and share moves value on-chain, turning engagement into ownership.

You’ll work on a live, high-growth product that blends design, performance, and crypto. The challenge is clear: make it buttery smooth across all devices and define how the next generation of social feels.
